A judge in Trinidad's capital, Port of Spain, has denied bail for three suspects accused of plotting a terrorist attack at New York City's John F. Kennedy Airport.

On Monday, the judge ordered them to remain in prison until a hearing is held on a U.S. request for their extradition.

U.S. authorities say the suspects - two Guyanese nationals, Abdul Kadir and Abdel Nur, and a Trinidadian, Kareem Ibrahim, - were seeking support from radical Islamic group, Jamaat al Muslimeen, that attempted a coup in Trinidad in 1990.

The three men and a fourth suspect, a U.S. citizen and former airport employee from Guyana, Russell Defreitas, had planned to blow up the airport by targeting the facility's underground pipelines of jet fuel.

Authorities say the plot, which could have destroyed the entire airport, never went beyond the early planning stage.
